Inventor: KITANO RIICHI
IPC: H02J7/34
Filed: 2008-06-03
Abstract: <P>PROBLEM TO BE SOLVED: To provide a DC backup power system, which is high in reliability on feed, and to provide a method of charging the same.  <P>SOLUTION: The DC backup power system includes components of a rectifier 2, which converts AC power from an AC power supply 1 into DC power and outputs it to a load 6, a battery pack 4, in which one or more storage batteries are connected in series, and a charger 3, which charges the battery pack 4. The battery pack 4 is connected, in parallel via a diode 5 which passes power only in the discharge direction of the battery pack 4, to a feed line from the rectifier 2 to the load 6, and the output upper limit voltage of the charger 3 is set to not more than a voltage where the absolute value of the forward voltage drop of the diode 5 is added to the set output voltage of the rectifier 2, and when charging the battery pack 4, the constant current charge by the set upper limit current is performed until the output voltage of the charger 3 reaches its upper limit, and after it reaches the upper limit value, it shifts to the constant voltage charge by the upper limit voltage, and further when the charge current is lower than the set lower limit current, the charge is finished.  <P>COPYRIGHT: (C)2010,JPO&INPIT

Title: Electrostatic loudspeaker
Inventor: NAKATANI TAKAO
IPC: H04R19/02
Filed: 2008-06-03
Abstract: <P>PROBLEM TO BE SOLVED: To linearly displace a vibrator while preventing the contact of the vibrator and an electrode.  <P>SOLUTION: The napped surface of a cushion material 40L is in contact with the vibrator 10, and the napped surface of a cushion material 40U is in contact with the vibrator 10. When the vibrator 10 is displaced in the direction of the electrode 20L, the napped layer 41L of the cushion material 40L is compressed by the displacement of the vibrator 10, and then the napped layer 41U of the cushion material 40U is expanded. Since the surface of the cushion material is uniformly napped and the napped layers 41L and 41U are elastic, the force of the part of the napped layers 41L and 41U to return to the original shape is equal without variation within the surface of the cushion material. When elasticity is equal within the surface of the cushion material, since the displacement of the vibrator 10 is not varied when the vibrator 10 is displaced by electrostatic force, acoustic signals are correctly reproduced when the acoustic signals are input.  <P>COPYRIGHT: (C)2010,JPO&INPIT
